CB6687-2L proposes real-time data quality stamp to identify the quality status of the data, combined with the hardware redundancy status, covering information such as channel failure, sampling deviation, range overrun, network status, etc., to ensure the reliability and usability of real-time data, and to improve the security of data references; it supports the historical record and retrospective analysis of the quality stamp and real-time values;

CB6687-2L implements Modbus, ProfibusDP and other network drive modules, realises data communication with third-party devices through open specification OPC client and server interfaces, adopts transparent network management technology, builds distributed engineering object real-time database, realises global consistency and unified interface between system data and external device data, and meets the multi-real-time nature of industrial data, Multi-semantic, multi-temporal and multi-scale information integration and interface opening requirements;

CB6687-2L provides distributed algorithm scheduling technology based on algorithm block encapsulation and data-driven, event-triggered, and conforms to the IEC61131-3 standard control programming language, integrating logic control, motion control and process control as a whole, and develops and implements support for graphical programming (function block diagram FBD, ladder diagram LD, and Shunyi control language SFC) and textual programming (structural text ST, command table IL) and multi-language programming, The integrated development environment supports graphical programming (function block diagram FBD, ladder diagram LD, and smooth control language SFC), text programming (structure text ST, instruction list IL), and multi-language hybrid programming, supports encapsulation, derivation, and reuse of control algorithms, and realises offline configuration, on-line configuration, off-line simulation, and on-line debugging of control algorithms, thus improving programming efficiency;
